Wide wavelength tuning of GaAs/Al[sub x]Ga[sub 1 - x]As bound-to-continuum quantum cascade lasers by aluminum content control
J. Heinrich, R. Langhans, M. S. Vitiello, G. Scamarcio, D. Indjin et al.
Tuning of the emission wavelength in GaAs/AlGaAs bound-to-continuum quantum cascade lasers with different Al mole fractions (x) is reported. By varying x in the range of 0.370.52, a shift of the emission wavelengths of over 4 [mu]m has been observed. Using this method, laser action in the range of ... [Appl. Phys.
